never heard of that model fiat, but i would say it is a standard reverse polarity system

i somehow found how it works :

1- there's 6 pins on front doors and 4 pins on rear doors

2- there's a relay with 6 pins (+12 , GND , 1M , 2M , 2 , 1)

3- the first pin of each door goes to 2M, and the second to 1M

4- the third and fourth pins are +12V and GND

5- the fifth pins of the front doors goes to relay pin (1) on relay and the sixth pin of the front doors goes to relay pin (2)

that's all i found know

ALL UK Fiats are MULTIPOINT NEGATIVE so i assume yours will prob be the same.

Only problem is which UK model is equivelent to yours?

The easiest option would be to test the wires coming out of drivers door with a electronic probe, the 2 correct wires will be the ones that lock/unlock the doors when you give them a ground with the probe
